SEAL PRESS.

Specification of Letters Patent.

Patented Apr. 18, 1922.

Application mea May 2a, 1920. serial No. 385,054.y

To all 'whom t may concern:

Be it known that I, EMIL DIETZE, a citizen of the United States, and resident of bor'- ough of Brooklyn, city of New `fork, in the county of Kings and State of New York, have invented certain new and useful Improvement in Seal Presses, of which t-he following is a specification, reference being had therein to the accompanying drawing.

This invention refers to a press forseal for many purposes, such seals 'as those made of lead, tin, wire, steel, etc., and more particularly it is useful with steel seals, and in that class with keylock seals so-called which are used with eliiciency and security on all kinds of boxes or packages bound with aAv metal strap, an example of such seals beingl .members of a strap with great force and effectiveness so that it Will be virtually impossible to pull them apart or dislodge the seal without breaking or cutting. The invention therefore consists essentially in the construction, arrangement and combination of the various parts, substantially as will be hereinafter more fully described and then claimed.

In the accompanying drawings illustrating my lnventlon: i

Figure 1 is an interior elevation of my improved press, with one side of the frame removed, certain parts being in section, and indicates the movable jaws in the position they occupy when they are open and before the beginning of the compressingoperation.

Figure 2 is a similar view of the` same parts shown in their active clamping or pressing position when closed and applying the seal to the strap.

lFigure 3 ,is a vertical sectional elevation on the line 3, 3,`of Figure 1.

Figure 4 is a perspective view of the overlapping ends of a box strap and one form of metal seal in readiness to be locked thereon.

Figure 5 is a perspective view of another example of keylock seal or fastener.

Figure 6 is a cross-section of the strap and seal on the line 6, 6, of Figure 2.

Similar characters of reference designate corresponding parts in the different views.

y A suitable frame is provided to support the essential members of the press and allow a free operation of the movable parts, and such frame may be made in many ways, but I preferably construct this main frame of the press to consist of two parallel plates 1, 1, that are secured to each other so as to leave an intervening space, open at the sides, which space is occupied in part by the movable jaws and their operating levers and in part by a stationary jaw or anvil, as 2, which is held rigidlybetween the plates 1, by means' of rivets orI other fastening means, 3, 3, that lpass through the plates 1y and jaw 2, the said jaw 2 being located near the edge of the frame so that it may be in such a position as to be properly related to the seal when the latter is being compressed by the movable jaws in performing their functions in proximity to the aw 2. The latter aw has preferably a recessed outer face 2a, formed between parallel flanges 12, 12, at the edges of said jaw, which flanges may be more or less jaws 4 by -means of pivots 10 that pass.

through the jaws 4 and the right-angled bends in bell-crank levers 8, which are situated in slots in aws 4, as shown clearly in Figure 3. The shorter arms of these bellcrank levers 8 are pivoted together by means of a pivot 9, whose ends enter and are arranged to travel freely in the straight grooves 11 formed on the inner opposing faces of the sides 1 of the main frame; while the longer arms of bell-crank levers 8 are extended outwardly to serve as operating handles for these movable compressing jaws.

The faces of jaws 4 that are opposite to each other and are adjacent tothe lixed jaw or anvil 2 are recessed at 6 with recesses sufficiently large to accommodate loosely the edges of the seal; and contiguous to these recesses 6 the jaws 4 are fashioned with projecting members or lips 7 that work opposite to, under and against the recessed face 2a of f which the press operates to unite it.

the. jaw 2 and have the function of compressing the seal and the overlapping parts of the band or strap together to form the keylock fastener, as I shall presently more fully specify.

In my co-pending application hereinabove referred to, Serial Number 248.796. I have described and claimed one form of keylock steel seal with which this press is particularly useful. This is illustrated in my present drawing. with particular fullness in Figures 4 and 6, where it is shown outside the press, and inFigures 1, 2 and 3. where it is shown in the press, and in its relation to the strap sections A and B yrvlith 11s form of seal consists of a plate C of steel or other metal or material, near one edge of which a pair of prongs or lips F, F, are cut out to leave openings b, while near the opl posite edge another pair of similar lips F,

are similarly cut out to Aleave openings b, there being therefore an unobstructed space between the opposite pairs of lips suflicient to allow the strap or its sections A and B to be inserted between them; or, when these lips F, F are bent outwardly to a right angle or thereabouts, the seal can be easily slipped over the overlapping sections A and B after and while the latter are on the bale or package, as will be clearly seen by reference to Figure 4, which indicates the over,- lapping sections A and B and the seal with *its struck-out prongs in readiness to be slipped down over the said sections, so as to take the position shown in Figure 1 where the press is about to operate` and in Figure 2 where the press is being applied.

Suppose now that the ress has its arts in the position shown in igure l, wit the handles wide apart and the movable jaws 4, 4, also open and wide apart that is to say in the position where the clamping lips 7, 7, are farthest from the face of jaw 2. After the seal is placed on the strap the press can readily be placed in position to embrace the seal and strap, for the recesses 6, 6, in the movable jaws allow the plate ,C of the seal plenty of room after jaw 2 rests on plate C as in Figure 1. If now we bring the handles together as in Figure 2, the jaws 4 will be moved more or less on their pivots 5, while the pivot pin 9 travels in the grooves 11 to the ends thereof and is stopped when it reaches that point, for the compression of the seal will then be complete, for the action of pin 9 in grooves 1l will push the pivots 10 in a direction away from grooves 11 and so rotate the jaws 2 on pivots 5 as to bring lips 7 against the seal. In this operation when the jaws 4 bring their lips 7 underneath and against the prongs or ears F and compress them below the strap sections A and B, .it will be evident that these prongs will catch the edges of the strap pieces and press said edges closely y together; and as the clamping of the press l continues` the edges of the sections A andy B will embed themselves in the openings b and be forced substantially through said openings, it being noted as seen in the sectional view of Figure 6 that directly at the edges of sections A and B where the strain on the parts is the greatest there will be for a very short distance transversely inwardfrom said edges a slight breaking or fracture of the sections A and B, but this fracturing will not be sullicient to weaken or injure the strap. but simply makes a tighter union of the parts, which are thus by the action of the press bound very closely and intimately together, s o that the fastener' cannot be dislodged from the strap except by cutting or breaking it off. The face 2 of jaw 2, with its-parallel flanges 12;` 12 forming a dished or curved recess, acts to curve the seall plate C as shown in Figure 2 in such a'manner as to hold it more tightljv on the strap and also to obviate projecting edges which might entangle other objects if the plate C were allowed to remain straight. but as to this there may be a wide latitude in the shaping and I do not wish to be restrictedin making same.

The press may obviously be used with many different'kinds of seals besides the particular keylock fastener just described.

Another similar form of keylock fastener is shown in perspective view in Figure '3. Here there is a plate D similar to plate C. and pairs of prongs or lips E similar to prongs or lips F; but the difference in the seals lies in the provision of largerl auxiliary or extension openings d'- in plate D contiguous to and communicating. with the openings e out of which the' lips E are struck. These additional communicating openings (Z from which the material has beenentirely removed afford room for the spreading of some portion of the tightly compressed points of straps A and B when the action it understood that the press may be used with any suitable kind o seal or other article with which it may be found to serve a beneficial purpose. Further in the press itself many changes are obviously possible in the shape, relation, proportions and arrangement of the mechanical elements. and f I reserve the liberty and privilege of making such variations and changes as the 'ciroum Astances of individual cases may require within said frame having an outer clamping face,

movable jaws mounted in the frame and having recessed projecting clamping members adapted to clamp over the fixed aw and engage articles between them and the outer face of the fixed jaw, bell crank levers piv oted to the movable jaws, and pivotal means for interpivoting said bell crank levers, said pivotal means sliding loosely in such guide in the frame.

2. Ina press, the combination of a. frame, a stationary jawin said frame having an outer clamping face, movable jaws mounted in the frame and having recessed clamping members which operate opposite to the outer face of the fixed jaw on opposite sides thereof, so as to engage said outer face and engage articles between them and the outer face of the fixed jaw,- operating levers for the movable jaws, means for pivoting said latter levers to each other, and a guide in the frame in which said pivotal means slides.

3. In a press,l the combination with a frame, of a fixed jaw having an outer clamping face, movable jaws` mounted in the frame and having projecting members which engage the outer face of the fixed jaw and clamp articles between them and said outer face, bell crank operating levers pivoted to the movable jaws, means for pivoting said operating levers to each other consisting of a sliding member, and a guide in the frame opposite to the fixed jaw, in which guide the slidinor member reciprocates.

4. Iii a press. the combination of a frame having parallel sides, a rigid jaw securely fastened between said sides and having a recessed outer clamping face, a pair of movable jaws pivoted between the sides and recessed to provide a lip that will overhang and clamp opposite to the outer face of the fixed jaw so as to engage articles between the same and the fixed jaw, bell crank levers pivoted to the .movable jaws, and pivoted to each other, and guiding means within the frame opposite to the fixed jaw for controlling the sliding movement of the common pivot of said bell crank levers.

5. In a press, the combination of a frame consisting of parallel plates having oppositely-located guide grooves, a. jaw fixed between said plates, a pair of movable jaws pivoted between said plates with their clamping members contiguous to the face of the fixed jaw, bell-crank levers'pivoted to the movable jaws, and having their longer arms serving as handles and their shorter arms pivoted together, and means for pivoting the latter consisting of a pin whose ends slide in the guide grooves of the frame and have a definite range of movement. j

In testimony whereof I hereunto a-fiix my signature.
